Automatically operating machines for producing paper vessels are known, which produce and at the same time fit together the individual parts in a combination of different operations, the bottoms being drawn and at the same time pressed into the wall in the combined machine; This machine is open to the objection that, when an interruption occurs in any of the operations, all other operating devices are likewise rendered inoperative, and the whole machine is put out of service, so that the effective output of the positively combined machine is considerably reduced.

Plants are likewise known, which comprise different machines partly interconnected by conveying means, the bottoms and the lids being, however, separately drawn on a drawing press and then piled in the assembling machine and automatically taken from this pile. By this, partly separate construction, the danger of interruption existing in the first combined construction and particularly great when the cardboard bottoms are drawn from material of inferior quality is overcome by employing the pile for feeding the drawn bottoms. However, it has been found that the automatic picking up of the conically pressed bottoms from the pile likewise causes interruptions, because the conical .bottoms, when piled, fit irregularly in one another. This is chiefly due to the fact that the drawn cardboard bottoms, after being stripped from the drawing ram, assume an oval shape in the longitudinal direction .of the fibres of the roll of cardboard. Moreover, an. operator is always required for building up the pile.

These objections are overcome by the machine according to the invention for inserting bottoms r and lids in finished vessel walls made of paper,

' for example, a fresh roll of cardboard is inserted in the drawing press or an interruption occurs, the assembling machine can continue to work with the wall winding machine, using up the piled stock, so that only on rare occasions a stopping of the whole plant is necessary, because the piling up of the bottoms and lids is omitted and consequently they cannot possibly jam. This is of great importance, because the glued paper web in the wall WlIldll'lf' machine will dry and result in a great loss in waste if the machine is stopped.

There is also the danger that the hollow bodies passing through the drying chamber dry too strongly and tear when the bottoms and lids are pressed therein, causing the vessels to leak.

For this reason the drying chamber is provided with a heat regulating device and a mois ture gauge, so that the hollow bodies always have the requisite moisture content when the bottoms and lids are inserted.

In the plant a sterilizing arrangement is connected up behind the assembling machine, and heated to about C. The finished paper vessels are sterilized in this sterilizing arrangement and fed to a known filling machine by a heated conveyor. The air heated for the sterilization is drawn off by a fan and blown into drying apparatus, in which the freshly wound sleeve-shaped walls are dried. The heated air from the sterilizer is also conducted into the feed channels for the bottoms and lids, so that a rational utilization of the heat is obtained.

The machine for pressing the bottoms and lids into the sleeve-shaped walls is provided with several operating points arranged one behind the other, for glueing the sleeve-shaped walls, feeding the bottoms and lids, pressing these into the walls, and so forth. The hollow bodies are successively fed to and removed from the working points at short intervals by a transverse and vertical feeding detice. The finished vessels are conveyed by the machine'through the sterilizer and thence to the filling machine. For each operation only one tool composed of two or more parts is employed for embracing or holding the sleeve-shaped vessels. The holding elements at the glueing point are shortened on both sides so that the hollow-body projects at least so far that, if no such body is fed, the holding element is not smeared by the glue applying member.

By constructing the machine and arranging the operating points in this manner only one tool is required for each operation, so that the cost of the machine is greatly reduced, whereas in the known revolver bottom inserting machines tools comprising six, eight or more parts are necessary for the single operation and, when producing vessels of different sizes the exchanging of the tools demands much time.

A machine for continuously inserting bottoms and lids in finished glued sleeve-like vessel walls made of paper, cardboard or the like, is illustrated by way of example in the accompanying drawings in which:--

Figs. 26, 27 and 28 show three different types of beading.

The machine aggregate comprises a winding machine 12 with drying apparatus 13, a bottom press 14, a lid press 15 and an assembling ma- The sleeve-shaped hollow bodies I wound on the machine 12 and which may be cylindrical or conical, are dried by means of hot air in the drying apparatus 13 connected with the machine 12. This hot air may be produced by means of electricity, gas or steam. From the drying apparatus the sleeve-shaped bodies are conveyed by a conveyor band 19 into the heated collecting channel 88 whence they are fed to the assembling machine 18, for pressing in the bottom or the lid. The bottoms 34, stamped out from a paper web and pressed to the desired shape by the-machine 14, are automatically delivered to an elevator 82 or the like and raised thereby. The elevator 82 delivers the bottoms 34 into a heated collecting channel 38, through which they are conducted in front of the bottom pressing-in ram 84 of the assembling machine 18 and after being previously glued are pressed into the hollow bodies 1. The lids with closing device are produced in the machine 15. The finished pressed lids delivered by the press 15 are raised by means of an elevator and discharged into a heated collecting channel 31. The channel 31 communicates with the machine and delivers the lids 34 in front of the ram 88 for pressing the lids into the hollow bodies I, the bodies having been previously glued.

The machines I2, 18, I4 and 15 are intercon (Figs. 5-8) nected and cooperate automatically so that, when the individual parts of the paper vessels have travelled along their prescribed paths, they are united on the'assembling machine to form vessels ready for dispatch, which are then delivered from the aggregate.

The channels 88, 3'! and 38 leading to the assembling machine are heated by hot air. The hot air is fed to the sterilizer 11 at a temperature of about C. by means of a pipe 88. The hot air discharged from the sterilizer I1 is drawn by a fan through the pipe 89 into the drying apparatus I3 and conducted from the pipe 89 through pipes 98 into the channels 31 and 38. The pipes 98 may be connected with the channels 31 and 38 at any desired point.

The finished vessels 9| are conveyed by a conveyor band 92 from the sterilizer TI to the filling machine.

The machine comprises a base frame I in which .the axles necessary for the drive are journalled,

a machine table 2 on which the lower halves 3 of the sleeve holders are adjustably mounted, a large vertically movable frame 4 with which the upper halves of the sleeve holders are adjustably connected and a conveying frame 6 extending transversely across the machinetable for conveying the wound sleeve-shaped bodies I made of paper, cardboard or similar material. The frame 4 comprises guide rods 8, an upper connecting plate 9, and lower'transverse connecting elements l8 and II. The rods 8 are vertically guided in bearings I2 and I3 fixed on the frame I. The movement of the frame 4 is effected by cams I5 fixed one on each end of the axle l4 and .35

adapted, during their rotation, to raise and lower the frame at predetermined intervals. When the frame 4 is raised the hollow bodies I are advanced one operating step by the conveying frame 6, whereas, when the frame 4 is lowered, the hollow bodies I are held between the holder halves 3 and 5. Whilst the sleeves 1 are being held in the different working steps the glueing, pressing-in of the lids and bottoms and so forth, are carried out. The upper halves 5 of the sleeve holders are connected with the upper plate 9 by brackets 16, whereas the lower halves 3 of the sleeve holders are fixed on the machine table 2 or on the frame I by brackets H. The brackets l6 and H are adjustable so that they can be set A to the size of the hollow bodies. The two-part sleeve holders 3, 5 are arranged side by side at equal-distances apart and can easily be removed from their brackets I6 and H and exchanged for dealing with hollow bodies I of another size. As many holders 3, 5 as there are operating points are usually provided in the machine. There may also be more holders 3, 5 than there are operating points. In this instance the holders 3, 5

which are not required can be disengaged or dismantled. In the transverse recess l8 of the table 2 the conveyor frame 6 is arranged between the lower-sleeve holder halves 3 fixed on the table 2, guided with its two ends in transverse guides l8 (Figs. 3, 5, 7, 8, 9 and 10). The frame 6 has pins 28, 28 or the like engaging with the transverse guides l9, l9. These guides are adjustable on transverse pieces l8, l8 of the rods 8, 8, so that the frames 4 and 6 can be raised and lowered at the same time (Fig. 5). On the end of the axle l4 projecting at one side of the machine a cam drum 2| is keyed, which actuates a rocker lever 22 connected with the frame 6 by a link 23 The frame 6 is reciprocated periodically by the cam drum 2| andthe lever 22. An

' ing in five separate operations.

r into the hollow body (Fig. 12).

lip and down movement is also imparted by the frame I to the conveyor frame 0 at the end of its movement, so that the frame 0 carries out a rectangular movement, uniformly spaced recesses 24, 23, 20, 21, 23 and 29 are provided in the frame 0 in which the hollow bodies I rest whilst being 7 bodies 'I are lifted out of the lower holder halves 3, whereupon the frame 3 with the hollow bodies I is shifted a distance 30 from one point of operation to the next (Fig. At the end of this movement the frame 4' descends with the conveyor frame 0 so that the hollow bodies I moved through the distance of one operative point are placed in the next following holder halves 3. During the descent of the frame I the holders 3, 5 are at the same time closed and the hollow bodies held for the next'operation. After the descent of the frame 3 it is returned into its initial position (Fig. 6). In this position the hollow bodies are placed by hand or automati cally into' the first recess .24 after each return movement of the frame 3. During each forward movement of the frame I the hollow bodies are moved on one operating point so that, when a hollow body has passed all the operating points, it is delivered finished into the last recess 29 in the frame 0.

In the drawings two methods of fixing the lids and bottoms 3| are illustrated. According to Figs. 12 to 15 the lid and the bottom are fixed in the hollow body by pressing and beading or fold- In the first operation the hollow body 1 is smeared by the glueing apparatus 32 with glue on its inner side at the ends 33 within the range of the lid. In the second operation the lid and bottom 3| are pressed In the remaining operations theedges 33 of the hollow bodies I are rigidly connected with the bottom by heading or folding (Figs. 13 to 15).

For beading a ram 09 may be employed having in its under face an annular groove I05 which serves for guiding the edge to be beaded One or several radial bolts IOI are rotatably mounted and have extensions I03 which can be fixed by means of set screws I00. The bolts.IOI have each a beading groove I 02 adapted to the shape the exposed portion of the beading groove I02 is worn, the bolt IN is turned so that a fresh portion of the groove I 02 registers with the groove I03 in the ram. If the whole of the groove I02 is worn ut, the bolt IN is renewed. The bolts IOI are de of high grade steel so that they will last as long as possible. According to Fig. 24 the two bolts I 0I.in the horizontal or vertical arrangement can be made in one piece. The number of bolts employed depends upon the size of the ram.

Other exchangeable elements can be inserted in the groove I03 of the ram instead of the bolts IOI. Thus, for example, fiat elements I03 can be inserted which have beading portions registering with the grove I03 (Fig. 24).

The lid flanges can at the same time be beaded into the sleeve edges with the beading ram (Figs. 26 and 28). 3

According to Figs. 16 and 17 the bottom and lid 34 are each provided with a conically drawn edge 33. These finished, previously pressed lids and bottoms 34 are pressed into the hollow bodies I by means of a correspondingly conical ram 30. The holders 3, I are provided with extensions at the operating points where the lid and bottom are'pressed into the sleeves, the outer edges of these extensions being fiush with the edges of the sleeves 1. These extensions have a bevel on the inner side corresponding to the conicity of the pressing ram 30 (Figs. 16 and 17). Thus, the originally cylindrical ends of the sleeves also become conical after the pressing in of the conical lid and bottom, this conical portion of their ends being limited by the bevel 00 in the extension 03. The extension 93 of the pressing-in ram 30 is resiliently mounted on one or both sides so that in the event of unequal length of the hollow body stretched position (Fig.

the extension 03 can yield and consequently the hollow body will not be crushed. Owing to the lids and bottoms being pressed under heavy pressure into the originally cylindrical ends of the hollow bodies I, a strong stressing is produced which ensures an absolutely reliable closure between the lid and bottom and the wall of the hollow body, such as can only be attained by com plicated beading in the case of cylindrically drawn bottoms. Moreover, the strength and stability of the vessel produced is increased by the conical ends.

The application of the glue, and also the remaining operations, is always carried out simultaneously on both sidesof the hollow body. The finished pressed lids and thebottoms are automatically fed through the channels 31 and 38 in front of the pressing dies 36 which are exchangeably fixed in sliding members 33. These sliding members 30 are connected with pairs of toggle levers 40 the latter interconnected by levers I actuated by cams 42. The pressing-in of the lid and bottom into the hollow bodies I is effected by depressing the toggle levers 40 into their The glueing device 32 comprises an eccentric axle 43;" which carries on its front end a glueing roller 44. The glue is applied on this roller 44 from the glue container by rollers l5, 40. During the application of the glue onto the inner side of the ends of the hollow body I the eccentric axles 43 are introduced from the side into the ends of the hollow body I so that they are in contact withthe walls of the bodies. whereupon by rotating the axles 43 the rollers roll on the inner side of the hollow bodies and thus glue the ends thereof.

The glueing device illustrated in Figs. 18 and 19 is more advantageous. According to this form of construction the glueing roller 05 is made of porous rubber or the like, onto the cylindrical outer surfaces of which the glue is applied from the glue container by means of rollers. The elastic glueing roller63 is fixed on the'end of a tubular member 34 which is rendered resilient by means of longitudinal slots. The front end 03 has the form of a hollow cone, into which the,

conical head 00 on the rod 01 is pressed. By

pressing the head 03 into resilient tubular member 04 the radius of its front portion and consequently of the rollers 00 is enlarged. Fig. 18

shows the glueing device in inoperative position. The glueing roller 63 in its inoperative position is slightly smaller than the hollow body I, sothat the glue cannot be scraped off the roller when introducing the glueing ram into the hollow body I. When it is desired to apply glue onto the inner side at the ends of the hollow body 1, the tubular member 64 is pushed into the hollow body 1 whereupon the head 66 of the rod 61 is pressed .into the conica-lly bored end 63 of the tubular member 64.

By forcing the conical head 66 into the tubular member 64 the front portion 63 of this member 64 will be enlarged, so that the elastic roller 65 bears against the inner wall of the hollow body 1.

The tubular member 64 is then rotated, causing glue to be applied to the inner side of the ends of the hollow body 1. After the glueing the rod 61 is pulled back and the member 64 returned into its initial position shown in Fig. 18.

This operation is repeated every time a fresh hollow body 1 is brought to this working point.

The tubular member 64 and the front aperture 53 are covered with a rubber cap so that no glue can penetrate into the member. The hollow body 1 is then fed to the pressing-in rams illustrated in Figs. 20 and 21, by means of which the conically pressed bottom and lid are pressed into the glued portion of the hollow body so that the ends of this body are likewise pressed conically outwards.

The ram 69 for pressing in the bottom also consists of a tubular member rendered resilient by longitudinal slots and the front end of which has a conical bore 10. As soon as the previously pressed lid 34 is placed onto theconical front end, the tubular member 69 is inserted into the end of the hollow body 1. By shifting the rod 1| its front conical end 12 is pressed into the bore 19 whereby the lid or bottom 34 is tightly pressed into the end of the hollow body 1. When the bottom or lid has been pressed into the hollow body 1, the rod 1| is pulled back, whereupon the frontend of the tubular member 69 resiliently contracts and the tubular member can easily be'moved back into the position shown in Fig. 20. This pressing ram prevents the glue applied to the inner surface of the sleeve, from being pushed inwards during the pressing in of the lid or bottom. The tubular member 64 of the glueing device and the tubular member 69 of the ram and also their rods 68 and 1| are mechanically actuated by the machine.

The holders 3. are shortened on both ends at the glue applying points so that the hollow body projects freely at both ends, and when no hollow body is fed the holders are not smeared by the glue applying roller 44.

The machine is driven by the pulley 41, on

the axle 48 of which a toothed wheel 49. is keyed which meshes with a toothed wheel 5| keyed on the axle 50. This axle 59 also carries another toothed wheel 52 which rotates the axle l4 through the intermediary of a toothed wheel 53. The toothed wheel 52 likewise drives a toothed wheel 55 on the axle 54 which actuates toggle levers 49 at one side of the machine, whereas the toothed wheel 53 by means of an intermediate toothed wheel 56 rotates a toothed wheel 51 keyed on an axle 58 which actuates the toggle levers 48 at the other side of the machine.

The machine operates in the following manner: A

It is assumed thatthe bottoms and lids are inserted as shown infFigs. 16 and 17. After the tools for the size of the hollow bodies 1 have been fitted and properly adjusted and a hollow body 1 has been placed in the first recess 24 of the conveyor frame 5, vthe machine is started,

whereupon the frame 4 is raised with the corn veyor frame 6. Owing to the raising of the frame 4 the holder halves 5 are lifted from the stationary holder halves 3 and opened. At the end of the upward movement of the frames '4 and 6 the frame 6 is shifted a distance 30 equal to the spacing of the holders. As soon as the frame 6 reaches its extreme advanced position. it is lowered with the frame 4. During the descent of the frame 6 the hollow body 1 is deposited in the first lower holder half 3. When the frames 4, 6 are lowered, the hollow body 1 is gripped by the holders 3, 5 and the glueing devices 32 become operative on both sides and the rollers 44 apply glue to the inner side of both ends of the hollow body 1. The pressing rams 36 are moved towards the hollow body 1 by the toggle levers 46 at the same time as the glueing device 32 is operated. When only one hollow body 1 has been fed the rams 36 run idle. Whilst the glueing devices 32 and the rams 35 are operating, the frame 6 in its lowered position is moved'back by the lever 22. During the return movement of the frame 6 the operation of the glueing devices 32 are carried out. As soon as the frame 6 has been moved back, the second hollow body 1 is placed in the recess 24, whereupon the. operation is repeated with the second hollow body 1. During this operation the first hollowbody 1 is moved on another step to the pressing rams 36 by the frame 6.

During the third operation the "first hollow body 1' is moved into the next operating point until the first hollow body has passed all the steps and is delivered into the last recess 29.

After the lid and bottom have been pressed into the hollow body the glue can draw and dry during the next operation.

Any desired number of operating points may be provided in the machine.

So that no lids and bottoms can pass from the channels 38 and 31 in front of the pressing rams whenno hollow bodies 1 are on the frame 6, slides 96 are provided which close the ends of the channels 31 and 38. i

The slides 98 are controlled by keys 93 the ends of which bear against the horizontal arms 94 of elbow levers 95. The upper ends of the elbow levers 95 are connected with the slides 96.

The arms 94 of the elbow levers 95 are continually pulled against the lower ends of the keys 93 by springs 91.

The keys 93 are vertically guided in bars or the like. The upper ends of the keys bear against the hollow body 1. When there is no hollow body between the holders 3, 5 the keys move upwards and the levers 94, 95 swing under the influence of the springs 91 causing the slides 98 to close the channels 31, 38 (Fig. 4a).
